Timken 2506 Manual Transmission Output Shaft Seal

The Timken 2506 manual transmission output shaft seal is built for Chrysler, Dodge, Jeep, and Mitsubishi applications that need a precise seal at the output shaft. It helps retain lubricant, block contamination, and maintain stable sealing performance in manual transmission service.

• Precision sealing design helps reduce lubricant escape and keep debris out
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed S-Nitrile inner diameter helps seal minor shaft imperfections
• Internal contamination exclusion system helps limit debris penetration that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to help manage heat build-up
• Outside diameter: 2.378 in. / 60.38 mm
• Shaft diameter: 1.563 in. / 39.57 mm
• Housing bore: 2.372 in. / 60.25 mm
• Width: 0.335 in. / 38.10 mm
• Helix type: CCW - Counter Clock Wise

Built for manual transmission output shaft sealing, this Timken 2506 seal uses S-Nitrile material and a reinforced case to support consistent fitment in service environments where heat, contamination, and shaft wear can affect sealing. It cross-references Catco 2506 and Quality-Built 15546 for the same application. Fits 1999-2003 Dodge Ram 1500 Van, 1987-1991 Jeep Wrangler, and 1983-1986 Mitsubishi Mighty Max with listed transmission applications, along with many Dodge, Chrysler, and Jeep rear output shaft configurations shown in the fitment data.

Common Problems This Seal Can Address

• Transmission fluid leaking from the output shaft area
• Contamination entering the rear of the transmission
• Seal wear caused by shaft imperfections or surface irregularities
• Heat-related seal deterioration around the output shaft
• Reduced sealing performance on older manual transmission assemblies

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. This seal is listed with a counter-clockwise helix type, so matching the transmission configuration is important for proper operation. Clean the bore and shaft surface thoroughly, inspect for scoring or excessive wear, and seat the seal evenly to avoid distortion during installation.

Quality Assurance

Timken oil and grease seals are engineered with precision sealing features, reinforced construction, and contamination control details to support dependable service in drivetrain applications. The 2506 part number is a direct reference for the listed manual transmission output shaft seal applications.
